When attempting to apply airborne virus detection derived from exhaled breath aerosol to collective monitoring of livestock, issues arise regarding quantitative evaluation values in addition to the difficulty of detection itself. Due to the influence of the behavior of many livestock, there is no moment when the entire measurement space, such as inside a livestock barn, becomes uniform. Therefore, even if air collection is performed at a large air flow rate of over 100 L/min, the amount of airborne virus detected is not constant because it is strongly influenced by livestock behavior near the collection point. Therefore, in this study, to develop an analysis method for collective monitoring of livestock through airborne virus detection, we attempted to understand epidemic trends based on the detection frequency when collecting multiple samples rather than quantitatively detecting the amount.
